【摘要】：养猪生产中猪饮水器用水中漏水将增加污水产生量,环境温度和供水水压及饮水器类型均会对饮水器总用水量产生重要影响。该文选择夏季不降温的保育猪舍,通过试验研究了不同饮水器和供水压力对保育猪用水量和浪费水量的影响。用水量和浪费水量每分记录1次。试验的第一个阶段,用10头/圈的保育猪比较了在水压为0.10,0.15和0.20 MPa时杯式饮水器和swing饮水器对用水量和浪费水量的影响;第二个阶段,用5头/圈的保育猪比较了在水压为0.10 MPa时带片swing饮水器和标准swing饮水器对用水量和浪费水量的影响。结果表明:在水压为0.1,0.15和0.20 MPa时,杯式饮水器每头猪的用水总量分别为16.2±3.0,30.3±8.1和38.3±4.8 L/d,swing饮水器的用水总量分别为5.7±1.0,8.7±1.9和10.3±0.4 L/d。在0.1,0.15和0.20 MPa下,杯式饮水器浪费水量/用水总量预测值分别为83.3%,85.1%和85.4%;swing饮水器浪费水量/用水总量分别为54.4%,48.3%和45.6%。带片swing饮水器每头猪用水总量(11.3±1.7 L/d)没有显著高于标准swing饮水器的用水量(9.4±1.0 L/d)(P0.05)。但是带片swing饮水器的浪费水量/用水量(60.2%)显著高于标准swing饮水器的浪费水量/用水量(46%)(P0.05)。因此,为了减少保育猪用水总量和浪费水量,应控制水压或者调节饮水器水流量至适宜值。在夏季不降温猪舍,与swing饮水器相比,杯式饮水器将增加用水总量和浪费水量。相对于标准swing饮水器,带片swing饮水器的使用没有减少水的浪费。
[Abstract]:The leakage of water used by pig drinking water in pig production will increase the production of sewage, and the environmental temperature, water pressure and type of drinking water will have an important effect on the total water consumption of drinking water. In this paper, the effects of different drinking water and water supply pressure on the water consumption and waste water consumption of conservation pigs were studied by using a conservation pig farm with no cooling temperature in summer. Water consumption and waste water are recorded once per minute. In the first phase of the experiment, the effects of cup drinking water and swing drinking water on water consumption and waste water consumption were compared at water pressure of 0.10,0.15 and 0.20 MPa with 10 pigs per circle. In the second stage, the effects of swing drinking water with slice and standard swing drinking water on water consumption and waste water consumption were compared at water pressure of 0.10 MPa with 5 breeding pigs per circle. The results showed that when the water pressure was 0.1, 0.15 and 0.20 MPa, the total water consumption per pig was 16.2 卤3.0, 30.3 卤8.1and 38.3 卤4.8L 路L ~ (- 1), respectively. The total amount of water used in swing drinking water was 5.7 卤1.0,8.7 卤1.9,10.3 卤0.4L, respectively. At 0.1, 0.15 and 0.20 MPa, the predicted ratio of water waste to total water consumption was 83.3%, 85.1% and 85.4%, respectively. The amount of water wasted by swing drinking water was 54.4%, 48.3% and 45.6% respectively. The total water consumption per pig with swing (11.3 卤1.7L / L) was not significantly higher than that of the standard swing (9.4 卤1.0L / d) (P0.05). But the waste water / water consumption of swing drinking water with slice (60.2%) was significantly higher than that of standard swing drinking water (46%) (P0.05). Therefore, in order to reduce the total water consumption and waste water, the water pressure should be controlled or the water flow of drinking water should be adjusted to the appropriate value. In summer no cooling pig house, compared with swing drinking water, cup-type drinking water will increase the total amount of water and waste of water. The use of a slice of swing drinking water did not reduce waste of water compared to standard swing water fountains.
